Graham Slee Novo Headphone Amplifier


SKU: N/A Categories: ,


The Novo headphone amplifier has a single chained phono (RCA) jack input allowing you to drive it from your favourite music source and then run another interconnect on to your main amplifier. It can also be fed from a pre-amp output or recording output.

Dynamic headphones of between 16 Ohms and 600 Ohms are driven to similar volume levels and the full rotation of the volume control can be used to make up for differences in headphone sensitivities.
